Annotated Snippet
What: /config/usb-gadget/gadget/functions/ffs.name
Date: Nov 2013
KernelVersion: 3.13
Description: The purpose of this directory is to create and remove it.
A corresponding USB function instance is created/removed.
All attributes are read only:
============= ============================================
ready 1 if the function is ready to be used, E.G.
if userspace has written descriptors and
strings to ep0, so the gadget can be
enabled - 0 otherwise.
============= ============================================
All other parameters are set through FunctionFS.Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
